Mind waiting for https://github.com/llvm/llvm-project/pull/85971 to land, then are you comfortable rebasing your changes on top of that? I'd wait until it lands; it's possible to rebase your branch on my branch BEFORE my branch lands, but IME if my branch gets updated before landing, it causes merge conflicts getting yours landed that are a waste of your time to resolve.
